Abstract
We construct a family of nonlinear q-ary codes obtained from the corresponding families of modified complex Butson–Hadamard matrices. Parameters of the codes are quite close to the Plotkin bound and in a number of cases attain this bound. Furthermore, these codes admit rather simple encoding and decoding procedures.
